UNITED STATES PATENT QFFICE.

CHARLES E. HITGHINGS, OF NEW YORK, N. Y.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 374,360, dated December 6, 1887.

Application filed June 25, 1886. Serial No. 206,223. (No model.)

To (ZZZ whom it may concern:

Be it known that I, CHARLES E. HI'IOHINGS, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Radiators, of which the following is a specification.

My invention is intended more particularly for hot-water radiators, although it may be embodied in radiators wherein steam is the heating-fluid; and the invention relates to radiators severally composed of a top and base or opposite headers, and tubes extending between and united at opposite ends with the top and base or headers; and the object of my invention is to provide for conveniently supporting the inlet-pipe,through which fluid enters the radiator, in such manner as to permit the free expansion and contraction of the inlet pipe or tube.

To this end my invention consists in the combination, in a radiator,with pipes or tubes and atop and base or oppositely-arranged headers, between which the pipes or tubes ex tend, the base or one header being formed with a cored passage or opening, of an inlet pipe or tube through which heating-fluid enters the radiator, and which is secured in the top or one header and has its other end sus tained by and self-adjustable in the said cored passage or opening.

In the accompanying drawings, Figure l is a sectional elevation of a radiator embodying my invention; and Fig. 2 represents a portion of the radiator shown in Fig. 1, illustrating a slight modification of my invention.

Similar letters of reference designate corresponding parts in both figures.

A designates the pipes or tubes of the radiator, and B O designate the headers between which these tubes extend, and with which the ends of the tubes are connected by steam-tight or water-tightjoints, the headers being unconnected, save by the tubes.

The headers B G constitute, respectively, the top and base of the radiator.

In this example of my invention the tubes are represented as secured in the headers by casting the metal of the headers around their end portions, and to facilitate the formation of a tight joint at the ends of the tubes the end of the tube may be provided with indentations, or circumferentially grooved, as at b, so as to form recesses into which the molten metal will run in casting the headers, and thereby hold the tubes firmly in the headers.

D designates an inlet pipe or tube, through which the heating-fluid passes upward to the top 13, and from the hollow top the fluid passes downward through the tubes A to the base 0, and thence escapes through a delivery-pipe screwed into the tapped hole or opening a in the base.. The fluid-inlet pipe D may at its upper end be screwed into the top or upper header, B, or it may be secured therein by casting in the same way in which the tubes A are secured; but the opposite or lower end of the inlet-tube"D is sustained by and selfadjusting in the passage or opening (I, cored within the base 0, and hence any straining of the joints, whether formed by casting the tubes A into the headers or by screwing them or otherwise securing them thereinto, by the expansion of the tube D is prevented.

In Fig. 1 I have represented the tube D as sustained by and self-adj ustable in the straight passage d through the base, and in Fig. 2 I have represented the tube D as having its bottom portion curved or bent outward laterally, and as sustained by and self-adjustable in the cored passage or opening (I, cored in the base. The end of the tube D is in this latter example of the invention presented laterally through the end of the base 0 for the attachment of the supply-pipe.

In making the radiator a loose fit of the tube D in the passage or opening d, which receives it, may be secured by coating the tube D with parting-sand before it is placed in the mold.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is

In a radiator, the combination, with tubes and a top and base or headers between which the tubes extend, and one of which is constructed with a cored passage or opening, of an inlet-pipe through which heating'fluid en ters the radiator, and which is secured at one end in the top or one header, and has its other end sustained by and self-adjustable in the cored passage or opening of the base or other header, substantially as herein described.

CHARLES E. HITGHINGS.
